Descaling
Hydro-mechanical descaling process. In hydro-mechanical descaling processes the jets are formed by special descaling nozzles which are arranged on spray headers in a so called descaling box (or mill descalers) through which the product (slab, strip, billet, bloom, beam blanket, etc.) travels.

Pickling of Hot Rolled Strip of Carbon Steel in Pickling Lines
Acids other than HCl or H2SO4 have been used to remove rust and scale from carbon steel. Citric acid, oxalic acid, formic acid, hydrofluoric acid, fluoboric acid, and phosphoric acid are all capable of removing mill scale from steel, but the rates of removal are generally not regarded as useful or economical for most commercial applications, especially continuous …

Hot rolled steel strips are produced by rolling of steel slabs of 210 mm thickness at 1150–1200 °C through roughing and finishing mills of a hot strip mill to a thickness of 1.6–6 mm.During hot rolling, some adherent oxides, known as scales, is formed on the strip surface in the reheating furnace prior to hot rolling due to high temperature oxidation.

CFD Analysis on a High Pressure Pump for Descaling in the …
The exposure of iron to oxygen in the air results in the formation of oxide scales on the steel surface. Therefore, it is very important to descale the steel to ensure a high surface quality in hot rolling mills. The descaler consists of several spray headers with nozzles that direct jets of water diagonally at the surface and typically operate at very high pressures of up to 400 bar. The …

Three types of iron oxide phases make up the scale on the steel surface. These are, with increasing oxygen content, wüstite, FeO, magnetite, Fe 3 O 4 and haematite, Fe 2 O 3.Usually a scale with all three types of oxide phases is present on the steel surface with wüstite being closest to the steel matrix, followed by the intermediate magnetite layer and the …

Billet Rolling Mill
For the production of raw material 130 mm x 130 mm to 160 mm x 160 mm, a billet rolling mill works in direct connection with the CC3 continuous casting system.With this plant configuration, we are able to reduce the material throughput time to 4 hours.. By shortening the heating times or deformation without heat loss a large amount of energy is saved.
